Trade Date:

Settlement Date (T+5):

May 10, 2007, which is the fifth business day following the initial sale of the Debentures. Under Rule 15c6-1 under the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Debentures prior to the third business day before the delivery of the Debentures will be required, by virtue of the fact that the Debentures initially will settle on a delayed basis, to agree to a delayed settlement cycle at the time of any trade to prevent a failed settlement. Purchasers of the Debentures who wish to make such trades should consult their own advisors.

Concurrent Offering:

Concurrently with this offering we will offer, by means of a separate prospectus supplement, Series B 6.125% Fixed-to-Floating Rate Junior Subordinated Debentures due 2067 in an aggregate principal amount of

$500,000,000.

Applicable Spread:

Applicable spread for the purpose of calculating the redemption price will be 0.50% in the case of a tax event; 0.50% in the case of a rating agency event; and 0.25% in all other cases.

Partial Redemptions:

With respect to any partial redemption, at least $25 million of the Debentures, excluding any Debentures held by us or any of our affiliates, must remain outstanding following such redemption.

Minimum Net Proceeds for Repayment of Debentures:

If we raise less than $5 million of net proceeds from the sale of qualifying capital securities during the relevant period, we will not be required to repay any Debentures on the scheduled maturity date or the next quarterly interest payment date, as applicable, but we will use those net proceeds to repay the Debentures on the next quarterly interest payment date as of which we have raised at least $5 million of net proceeds.

Replacement Capital Covenant:

A replacement capital covenant described in the preliminary prospectus supplement will apply until May 15, 2067.
